Looking through the various manufacturers sites it is quite hard to know which lens is good and which isn't.

I suppose your ultimate use is the key factor to determine a type of lens.

So perhaps that should be defined as best for a Canon 5D (that limits it as its a 35mm sized sensor), for terrestial landscape type images and also for widefield Milky Way type images.

So far talking to the pros at the Malins Awards Phil Hart and Alex the Nikon 14-24 and the Canon 24mm F1.4 seem hot.

Any thoughts?

Greg.
